Act

Franz Dischinger worked and researched in Germany in the beginning and middle of the 20th century in the field of reinforced concrete construction . He achieved outstanding results in reinforced concrete shell construction , in the prestressed concrete method , for the development of modern cable-stayed bridges and in the theory of the plastic behavior of concrete. He designed new types of prestressed concrete bridges and, together with Ulrich Finsterwalder, constructed thin dome shells and barrel roofs. The domes of the Großmarkthalle in Leipzig are an example of the reinforced concrete shell construction that he played a key role in developing . In 1934 he patented his new construction method for prestressed concrete bridges . In 1936/37 he planned the station bridge in Aue (Saxony) based on this patent, the world's first prestressed concrete bridge without a composite .

There is a “differential equation according to Dischinger” or “Dischinger equation”, which deals with the creep of concrete.

Life

Franz Dischinger was the son of a superstructure controller in Baden. He spent his childhood in Karlsruhe , where he also went to high school. From 1907 he studied civil engineering at the Technical University of Karlsruhe , among others with Friedrich Engesser and Karl Heun . During his studies he gave tutoring and revision courses for his fellow students. In 1911 he passed the main diploma examination "with distinction".

After a short job at the Vollrath construction company in Wesel , Dischinger did his military service as a one-year volunteer in Munich . He then joined the construction company Dyckerhoff & Widmann in Wiesbaden-Biebrich in 1913 , where he worked as a structural engineer and designer until 1933 . As part of this activity, Dischinger and Walther Bauersfeld developed the so-called Zeiss-Dywidag shell construction from 1922 . In 1929 he received his doctorate from the Technical University of Dresden under Kurt Beyer with a dissertation on polygonal bowls, and in the following year he won first prize in a competition of the Prussian Academy of Building with a treatise on "Reinforced concrete shells as space carriers".

On August 1, 1933, Dischinger took over the chair for solid construction at the Technical University of Berlin as the successor to Hermann Boost and from then on devoted himself primarily to theoretical questions of construction. In 1937/1939 he published groundbreaking treatises on the theory of creep and shrinkage of concrete. Due to a chronic illness, Dischinger retired early on April 1, 1951 .

tomb

His grave is in the municipal forest cemetery Dahlem in Steglitz-Zehlendorf. Until 2015 it was dedicated to the city of Berlin as an honorary grave .

Honors

In memory of Franz Dischinger, the board of the German Concrete Association created V. in 1953 a Dischinger Prize for outstanding graduates of the TU Berlin specializing in reinforced concrete construction. In 2005 this award was abolished in favor of a newly created innovation award for construction technology .

In 1956 a bridge in Berlin-Spandau was named after him, the Dischinger Bridge .

A portrait head in bronze, created in 1951 by the Berlin sculptor Erich Fritz Reuter , is located in the Humboldthain building complex of the TU Berlin , Building 13b, in the Institute for Civil Engineering, Department of Design and Construction .
